luivinoriiicd n rnhiio cushion H et the top o` he cylinder to preventany accidcnial, Contact between .hc piston hood sind c linder head. Ihave also shown the cylindbcr with n cut-out portion l, so located withreference lo the normal position of the two surfaces ne: to preventefi'ectivc action of any kind except in the curo of nhnorrnnl shock. lincose this feature is not desirable, the pinton hond ii min hc adjustedby means of the screw .il und nutRJ lf the piston hond is screwed upafconsidcrnble distance inFig. 2, the ineciuinisin there shown willlie-substantmlly that of Fi 4 in operation.

En Fig. 3 I inve shown a modification wherein the piston head E isprovided with arubber' tip L und normally operates in the auxiliarycylinder M. In cose of n moet extrnordinarv 'shock however, the rubbertip L fits imo the o ning N und un absolute mpmion of? e air is producedwithout any chance of escape because of the pockings O between theauxiliary cylinder M und the mein cylinder D.

Any chenges may be made in the portierin construction Shown sindillustrated withoutdeparting from the spirit of my invention.

I cioim: 1. The combination of tv-'o member?, one
